COMBINED EVAPORATOR, BAKER, AND VENTlLATOR FOR COOKING-STOVES. I

SPECIFICATION forming part of Letters Patent No. 489,990, dated November4, 1890.

` Application filed July 1', l1890. Serial No. 357,449. (No model.)

To all whom it may concern:

Be it known that I, JAMES WILLIAM ALLEN, residing at Eureka Springs, inthe county of Carroll and State of Arkansas, haveinv'entedanewandusefulCombinedEvaporator,Baker, and Ventilator forCooking-Stoves, of which the following is a specification.

My invention has for its object to provide a vsuitable Ventilatingdevice formed of' a box or drum adapted to be set over the stove andparticularly pointed out in the claims, refer-y ence being had `to theaccompanying drawings, in Whichv Figure 1 is a perspective View ofmyimprovement as applied for use. Fig. 2 is a lonn gitudinal sectionthereof; and Fig. 8 is a transversesection on the line 3 3, Fig. v2.

In the accompanying drawings, inA which the same reference marksindicate like parts in all the figures, A denotes a cooking-stove of theordinary construction, upon the top of which is supported my improvedVentilating device, which consists of the box or drum B, of a sizesuliicient to lap over the front and the ends of the stove-top, wherebyair-inlets b b are formed, and in which dampers b2 are provided over theinlets b b', whereby said inlets may be closed when desired, a damper bbeing also provided for the inlet b.

C indicates a'series-of telescopic pipesections joined with the upperend of the box B and connecting same with the chimney-flue, as shown. Ifdesired, however, the pipes C may be joined with the smoke-pipe c of thestove by any suitable connection, and thereby avoid the necessity ofcutting another opening in the flue. I prefer, however, to arrange Saidpipes separate, as shown.

D indicates a damper arranged in the pipe C just above its connectionwith the box B,

The box B is formed With a series of ledges b5 b5, which serve assuitable supports for evaporating pans or frames, which can readily beslipped into position .through a suitable door E, hinged upon one end ofthe box, as shown.

It will be understood that the horizontal portion C of the pipe C isheld from movei ment and that the telescopic sections end c3- low theupper joint C2. To the section C3, I

attach the ends of two ropes or chains F, which pass over pulleys ff andhang down within convenient roach of a person, suitable handholds ortassel; being formed on the ends of said ropes. By this arrangement itwill be seen that when desired the operator by pulling upon the cordscan raise the box up above the stove, (see dotted lines, Fig. 3,) so asto admit of ready access to the top of the same. Any suitable means maybe provided for holding the said device in its .elevated position.

In connection with the above-described device I employ a baking-oven Gr,adap l'ed to be placed upon the stove over the openings, and which isformed with a series of divisions g g, so as to bake several tiers atone time. By this arrangement it will be seen that when the baking-ovenis used that by letting down the box B over the same and closing thedampers all the heat from the top of the stove is concentrated withinsaid box, thereby baking in a Inuch quicker time than usual. It willalso readily appear that during ordinary cooking the box B may be letdown over the several pots, and thereby carry all the odors directlyinto the chimney-iiue.

Having thus described my invention, what I claim, and desire to secureby Letters Pat or close said inlets, substantially as and for,

the purpose described.
